The article examines results of studies on the effect of temperature, amount of carbon and pressure on the possibility of obtaining iron silicides and gaseous magnesium by carbon-Thermal reduction of silicon and magnesium oxides containing in chrysotile-Asbestos waste products. The studies were carried out using the HSC-6.0 software package (Outokumpy) and the second-order rotatable designs (Box-Hunter plans). It has been established that technology allows us to increase αSi(al), for example, at 1400 C from 89.6 to 96.75%, reduce undesirable losses of silicon with gaseous SiO from 8.97 to 2.08% and slightly increase αMg(gas) from 97.41 to 97.54%. The alloy formed at 1300 C contains 28.7% of silicon and corresponds to FS25 grade ferrosilicon.
